[Buildroot] [git commit] bind: fix static openssl linking

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=26aefa672c96caefc17adf59a9ab3d327114ad36
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Apparently LIBS (environment) isn't pushed to LIBS (autoconf) for the
tests, hence when static linking openssl it misses libz and assumes some
basic digests required for ecdsa support are missing, which is false. Fixes:
